Abstract

In one aspect of the present invention, an apparatus is provided for testing a plurality of devices. The apparatus, in one embodiment, comprises a controller, a device identifier capable of identifying each one of a plurality of devices as one of a plurality of device types, and a plurality of test heads. Each test head is capable of testing each one of the devices independently of the rest of the plurality of test heads responsive to the identification of each device by the device identifier and under the control of the controller. In a second aspect of the invention, a method is provided for testing a plurality of devices. The method, in one embodiment, comprises placing the plurality of devices identified into a plurality of test heads, each device being identified as one of a plurality of predetermined device types and being placed in a respective test head; and directing the testing of each device independently of the testing for the remaining devices responsive to the respective identification of the device, the direction for the testing of each device coming from the same controller.

Claims

1. An apparatus comprising:

a central controller;

a device identifier to identify each one of the plurality of devices as one of a plurality of device types;

a plurality of test heads, each test head to test each one of the devices independently of the rest of the plurality of test heads responsive to the identification of each device by the device identifier and under the control of the controller; and

a server to identify a set of instructions to the controller for one of the plurality of test heads to test one of the devices independently of the rest of the plurality of test heads, the set of instructions to be based upon an identification of a device of the plurality of devices as one of the plurality of device types;

wherein the device identifier is to identify at least one of the plurality of devices prior to inserting the at least one of the plurality of devices into one of the plurality of test heads.

2. A method to test a plurality of devices comprising:

placing the plurality of devices identified into a plurality of test heads, each device to be identified as one of a plurality of predetermined device types and to be subsequently placed in a respective test head;

identifying a plurality of sets of instructions to a central controller to direct the test of each device independently of the testing for the remaining devices, each set of instructions being based upon a device being identified as one of a plurality of predetermined device types; and

directing the testing of each device independently of the testing for the remaining devices responsive to the respective identification of the device, the direction for the testing of each device coming from the controller.

3. An apparatus comprising:

a device identifier to identify a device;

a plurality of test heads comprising a first test head to test the device independently of a second test head; and

a central controller coupled with said device identifier and with said plurality of test heads to direct testing of the device according to a testing protocol based upon identification of the device;

wherein the device identifier is to identify the device before insertion of the device into the first test head.

4. The apparatus of claim 3, wherein the device comprises a mobile processor board.

5. The apparatus of claim 3, wherein the testing protocol comprises a protocol to emulate a test hardware function with the first test head.

6. The apparatus of claim 3, wherein said controller comprises part of a test bed, wherein said test bed comprises:

a power supply coupled with said plurality of test heads; and

a communications interface coupled with said controller.

7. The apparatus of claim 3, further comprising a server through which the test bed controls said plurality of test heads.

8. The apparatus of claim 3, wherein said device identifier comprises:

a serial number reader to determine a serial number of the device; and

a product identifier to identify the device as a device type.

9. If The apparatus of claim 3, further comprising a server coupled with said controller to associate testing protocols with the device based upon the identification.

10. An apparatus comprising:

a device identifier to identify a device;

a plurality of test heads comprising a first test head to test the device independently of a second test head;

a server coupled with said device identifier to associate a testing protocol with the device based upon an identification of the device; and

a central controller coupled with said device identifier and with said plurality of test heads to direct testing of the device according to the testing protocol;

wherein the device identifier is to identify the device before insertion of the device into the first test head.

11. The apparatus of claim 10, wherein the testing protocol comprises a protocol to emulate a test hardware function with the first test head.

12. The apparatus of claim 10, wherein said controller comprises part of a test bed, wherein said test bed comprises:

a power supply coupled with said plurality of test heads; and

a communications interface coupled with said controller.

13. The apparatus of claim 10, further comprising a server through which the test bed controls said plurality of test heads.

14. The apparatus of claim 10, wherein said controller is coupled with said plurality of test heads to direct testing of the device by the first test head independently of testing of a different device by the second test head.

15. A method, comprising:

identifying a device;

placing the device in a first test head of a plurality of test heads coupled with a central controller, subsequent to said identifying; and

directing a test of the device via the controller, independently of testing of a second device by the controller, in accordance with a testing protocol based upon said identifying the device.

16. The method of claim 15, wherein said identifying a device comprises reading the serial number of the device.

17. The method of claim 15, wherein said identifying a device comprises predetermining an identity of the device.

18. The method of claim 15, wherein said directing a test of the device comprises identifying a test protocol for the first device based upon said identifying the device.

19. The method of claim 15, wherein said directing a test of the device comprises identifying independently of directing the testing of the second device.

20. The method of claim 19, wherein directing the testing of the second device comprises directing the testing of the second device in accordance with a different test protocol.

21. The method of claim 15, wherein said directing a test of the device comprises emulating a test hardware function with the first test head.

22. A method, comprising:

identifying a device;

placing the device in a first test head of a plurality of test heads coupled with a central controller, subsequent to said identifying;

associating a testing protocol with the device based upon said identifying the device; and

directing a test of the device via the controller, independently of testing of a second device by the controller, in accordance with the testing protocol.

23. The method of claim 22, wherein said directing a test of the device comprises identifying a test protocol for the first device based upon said identifying the device.

24. The method of claim 22, wherein said directing a test of the device comprises identifying independently of directing the testing of the second device.

25. The method of claim 24, wherein directing the testing of the second device comprises directing the testing of the second device in accordance with a different test protocol.

26. The method of claim 22, wherein said directing a test of the device comprises emulating a test hardware function with the first test head.
